Dec, 5 193$. R. J. SWANSON zgww w WATERPH 0 OF CONTAINER Filed Dec. 4, 1936 ilii iiifi Patented Dec. 5, 1939 UNITED STATES PATENT OFFICE WATERPROOF CONTAINER Reinhold J. Swanson, Chicago, Ill.

Application December 4, 1936, Serial No. 114,179 4 Claims. (01. 150-s)' The invention relates to waterproof containers for carrying such articles as cigarettes, matches, jewelry, money, etc., and to a structural element thereof and to the method of forming such part;

the principal object of the invention being to provide a container that is waterproof and shaped so that it may be carried in a suitable pocket in a bathing suit or strapped to a portion of the users body; and which may be provided with a compact or vanity case formed in the closure'for the container. It relates,'further, to the metallic liner for the wall of the opening of the container.

The other objects of the invention are to obtain cheapness of construction, durability, tight l5 sealing of the closure, and to provide a metallic liner for the opening which shall be readily insertable and cooperate with the closing cap to form a perfect seal without requiring the use of a gasket.

The invention is fully hereinafter described,

and is illustrated in the accompany drawing, in which- Fig. l is a View in perspective of the container; Fig. 2 is a longitudinal section of the container through its aperture-the closure therefor being shown detached and in elevation;

Fig. 3 is a transverse sectional view through the opening, the closure being shown as applied; Fig. 4 is a detail transverse section on the same plane as Fig. 3, showing a modified form of construction;

Figs. 5 to 8 represent the blank of a metallic element of the device and forming dies therefor;

and

Fig. 9 is a view in perspective of such element.

This application is in part a continuation of my application for improvements in Waterproof containers filed September 30, 1933, Serial No. 691,611.

In the embodiment of the invention as illustrated in the accompanying drawing the container, generally designated by the numeral l0, takes the form of an oblong box, one of the faces ll of which may be slightly concave to adapt it to fit snugly against the portion of the users body to which it may be secured, and the concave wall may be provided with a transverse channel 12 to accommodate an attaching strap (not shown). The front or outer wall l3 of the container is provided with a circular aperture,

generally designated by the numeral M, preferably located adjacent one end of the device and being of sufficient diameter to give convenient access to the interior for entering or removing the articles to be carried.

The container is preferably seamless, and is formed of soft rubber, the'rubber, however, being of sufificient hardness to enable the containerto maintain its shape in normal usage. The outer wall of the container, in the vicinity of the aperture I4, is thickened to form an annular flange 15 which may, and preferably does, extend both outwardly and inwardly beyond the surfaces of the wall in which it is formed. The cap It for this aperture has an annular flange I! for inter- 10 fitting the aperture, and a lateral annular flange I8 for engaging the outstanding portion S9 of the flange I5.

Some form of threaded engagement of the flange H with the wall of the aperture [4 is 15 provided. In the construction of Fig. 4 continuous threads are formed directly in the wall of the aperture, corresponding threads being formed on the closure flange ll. Preferably, however,

a metallic liner 25), for the wall of the aperture,

- other, 24, to enter an annular channel 25 in the circumferential face of this opening. 30

The liner 20 is further provided with an annular series of instanding studs, as 25, for engaging in a series of short helically disposed channels 21, formed in the outer face of the flange ll of the cap l6 and extending from its inner mar- 35 gin, and at their inner ends being inclined to a common radial plane of the flange. These cooperating studs and channels providing a screwthreaded action for drawing the cap tightly against the outstanding flange of the aperture to provide a watertight seal, the straightened ends of the channelsserving as a lock to prevent accidental loosening of the cap.

The cap I6 is preferably formed of a hard material, synthetic resin having thus far been used 45 the rib 33 at the end of the punch, traveling in the slot 34, forms a tenon 22 on the blani: being stamped, and a mortise 2! on the following blank. When the punch has forced the floor 3i of the matrix against a stop (not shown), the studs 2% are formed by suitable means provided on the die faces. from the dies shown in Fig. 5, has a form such as shown in Fig. 6.

The channel shaped blank of Fig. 6 is then placed. in a device, such as shown in Fig. '7, which has a semi-circular matrix 35 and a complementary punch Elli. The punch is forced into the matrix by a hand lever 31, being guided in its vertical movement by a cross-head 38. In this operation the blank takes the form shown in full lines in Fig. '7.

The upstanding ends of the blank are then manually bent inwardly, as shown in dotted lines in Fig. 7, and another matrix, 42, descends by (v housed within its aperture, as indicated in Fig. 4;

this aperture being inclosed by a suitable lid attached to the inner margin of the flange ll, here shown as externally threaded. This lid is preferably given the form of a mirror. When the compact is not present a mirror lfi may be secured against the inner face of the cap I6 "by snapping it past the lugs ll.

The disclosed embodiments of the invention are typical, but may be varied from in practice, and

' the seal of this invention may obviously be used scribed formed of soft rubber and having a cirfor other waterproof containers, such as ice packs,

hot water bottles, etc.

I claim as my invention: 1. In combination, a receptacle of the class'decular opening surrounded by an axially thickened integral rim having an annular channel in its inner face, a transversely split metallic liner for the rim having outstanding marginal flanges The finished blank, as it comes for engaging the channel and inner face of the rim and an annular series of instanding studs, a rigid cap for and being of greater diameter than the opening and having an annular instanding flange for interfitting the liner, and a series of helically disposed grooves for engaging the studs.

2. In combination, a receptacle of the class described formed of soft rubber and having a circular opening surrounded by an axially thickened integral rim having an annular channel in its inner face, a transversely split metallic liner for the rim having interlocking ends and an outstanding flange at its outer margin for engaging the channel and an annular series of instanding studs, a rigid cap for and being of greater diameter than the opening and having an annular instanding flange for interfitting the liner, and a series of helically disposed grooves for engaging thestuds, such grooves entering from the inner end of the flange and at their inner ends being deflected to a common radial plane of the flange.

3. In combination, a receptacle of the class described formed of soft rubber and having: a circular opening surrounded by an outstanding internally channeled flange, a split metallic liner for the opening having an outstanding flange at its outer margin for engaging the channel and an annular series of instanding studs, a rigid cap for and being of greater diameter than the opening and having an annular instanding flange for interfitting the liner, and a series of helically ping and directly engageable with the margin of the opening.
